HOT-WATER CAN WASHER.

Application filed November 15, 1924. Serial NO.750,172.

This invention relates tocan washers and aims to provide novel means whereby hot water may be forced into a milk can or the like, in a fine spray to cleanse the inner walls of the can.

Another object of the invention is to provide a device of this character having means to cause the cleansing fluid to pass into the can under treatment, under high pressure to further insure the cleansing of the can.

A still further object of the invention is to provide means whereby can tops may be positioned on the device for cleansing.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

' Referring to the drawing:

Figure 1 is an elevational View of a device constructed in accordance with the invention.

Figure 2 is a sectional view taken on line 22 of Figure 1.

Fig. 3 is a detail view of the revolving can support.

Referring to the drawing in detail, the device includes a frame indlcated generally by the reference character 5 which frame is rectangular in formation and includes a shelf 6 curved as at 7 to provide a seat for the tank 8 that supplies the burner 9 with fuel.

Supported by the frame is a boiler 10 that is disposed direotl over the burner 9 so that water in the boiler 10 may be heated by the burner.

This boiler is provided with a conical bottom 11 which has communication at its upper end with the atmosphere through pipe 12, so that fumes from the burner may pass off from the interior of the conical bottom. A cap indicated at 13 closes the filling open ing of the boiler.

Forming a part of the supporting frame 5 is a pipe 14 which communicates with the boiler through the pipe 15, the pipe 14 being supplied with check valves 16 and 17 so that water may be forced from the pipe 14, but restricted from reverse movement therethrough.

Supported by the pipe 14 is a pump indicated at 18 which is in communication with the pipe 14 the pump being of the usual construction and adapted to draw fluid from a supply tank and force the fluid through the nozzle and into the can being washed.

Communicating with the pipe 14 through pipes 19 and 20, is a nozzle supporting pipe 21 carrying the nozzle 22 which is adapted to spray the cleaning fluid onto the inner surface of the pan being washed.

The support for the can being washed is indicated at 23 and is provided with an opening through whichthe pipe 21 extends. Mounted within the support 23 is a rotatable support 24 which is of a diameter to receive the mouth of a milk can to support the same while undergoing the cleaning treatment.

An exhaust pipe indicated at 25 also communicates with the support 28 and provides means whereby the water collecting in the support 23 may be carried off therefrom and deposited in the tank 26, which is supplied with a drain valve indicated at 27. At the lower end of the pipe 21 is a spigot 26 which may be turned to drain the pipe 21 and pipe 20 should it be desired to remove water from the pipe during cold weather to insure against freezing and breaking of the pipes.

In order that can closures may be conveniently cleaned by this apparatus, a tubular supporting member 27 is provided which tubular supporting member is of a diameter, at its upper end, to receive a can closure in a manner as shown in dotted lines in Figure 1 of the drawings. The lower end of the tubular supporting member 27 is of a diameter to fit within the support 23 to hold the same in position.

In the use of the device, the boiler 10 is filled with water and the burner lighted to heat the water in the boiler. "When the temperature in the boiler has reached the desired degree, the pump 18 may be manually operated to draw fluid into the pump whereupon the pump may be operated to force the fluid into the pipe 19 and into the pipes 20 and 21 and nozzles supported at the upper end thereof, where the fluid is sprayed onto the wall of the milk can being washed.

I claim A can washer comprising a supporting frame including a pipe; extending trans versely of the frame, a water tank connected to one end of the pipe, a own suppont supported at the opposite end of the pipe, a pipe extending upwardly through the can support and having a nozzle at its free end adapted to spray a can positioned on the can support, a pump supported intermediate the ends of the first mentioned pipe, and in communication therewith, said pump adapt ed to draw liquid fremthe tanlz and force the liquid th iou gh the pipes and into the 10 nozzle.

In testimony that I claim the foregoing asm own, I htive hereto aflixed my signa-- ture.
